Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims benefit of Chinese patent
application CN 201510227740.3, entitled "Color Filter and
Manufacturing Method Thereof, Liquid Crystal Display Panel" and
filed on May 6, 2015, the entirety of which is incorporated herein
by reference.
FIELD OF THE INVENTION
[0002] The present disclosure relates to the technical field of
liquid crystal display, and particularly to a color filter and a
manufacturing method thereof, and a liquid crystal display
panel.
BACKGROUND OF THE INVENTION
[0003] The liquid crystal display device has substituted
traditional cathode-ray tube display device gradually and has been
widely used in tablet television, personal computer, mobile display
panel and other products by virtue of its advantages of low
radiation, small volume, and low power consumption.
[0004] With the improvement of the resolution of the Liquid Crystal
Display (LCD), the size of a single sub pixel is becoming
increasingly small. As shown in FIG. 1, when the light emitted by
the backlight source enters into a sub pixel B with a relatively
large inclining angle, the light would pass through the sub pixel B
in the active area, and at the same time, part of the light would
incorrectly enter into a color resistance layer of a sub pixel A
that is adjacent to the sub pixel B after passing through the
liquid crystal molecule layer. Under such circumstances, the colors
displayed in the LCD would mix with one another. Consequently,
under wide viewing angles, the colors presented by the LCD would
have a serious deviation. That is, there would be the color shift
problem in the LCD under wide viewing angles.
[0005] In the prior art, the color shift problem of the LCD under
wide viewing angles is generally reduced through increasing a width
of a black matrix thereof in order to guarantee that other optical
properties of the display panel are not changed. In this case,
however, the aperture ratio and the penetration of the display
panel would be reduced inevitably.
SUMMARY OF THE INVENTION
[0006] The present disclosure aims to solve the technical problem
of color shift of the liquid crystal display panel in the prior art
under wide viewing angles. In order to solve the aforesaid
technical problem, one embodiment of the present disclosure first
provides a color filter, comprising a color resistance layer, a
flat layer, and a first black matrix, wherein said flat layer is
coated on said color resistance layer, and said first black matrix
is arranged in said flat layer.
[0007] According to one embodiment of the present disclosure, said
first black matrix is formed on said color resistance layer through
printing or photolithography.
[0008] According to one embodiment of the present disclosure, said
first black matrix is formed through carbonizing said flat layer at
a position corresponding to a data line.
[0009] According to one embodiment of the present disclosure, said
color filter further comprises a second black matrix, which is
formed on a glass substrate, and said color resistance layer is
coated on said second black matrix and the glass substrate.
[0010] According to one embodiment of the present disclosure, said
color filter further comprises a common electrode layer, which is
formed on said flat layer.
[0011] The present disclosure further provides a liquid crystal
display panel, which comprises the color filter as mentioned in any
one of the above claims.
[0012] The present disclosure further provides a method for
manufacturing a color filter, and the method comprises the
following steps:
[0013] forming a color resistance layer, and then forming a first
black matrix on said color resistance layer; and forming a flat
layer on said first black matrix and said color resistance
layer.
[0014] The present disclosure further provides a method for
manufacturing a color filter, and the method comprises the
following steps:
[0015] forming a color resistance layer, and then forming a flat
layer on said color resistance layer; and carbonizing said flat
layer at a position corresponding to a data line so as to form a
first black matrix in said flat layer.
[0016] According to one embodiment of the present disclosure, said
flat layer is carbonized by laser irradiation at said position.
[0017] According to one embodiment of the present disclosure, the
method further comprises a step of forming a second black matrix on
a glass substrate before said color resistance layer is formed.
[0018] According to the present disclosure, the critical angle of
the color shift phenomenon of the color filter can be improved
effectively, and thus the color shift phenomenon of the liquid
crystal display panel under wide viewing angles can be alleviated.
Meanwhile, according to the present disclosure, the thickness of
each layer of the color filter and the width of the black matrix do
not need to be changed, and thus other optical properties of the
liquid crystal display panel would not be changed. Moreover, since
the width of the black matrix is not increased, the aperture ratio
and the penetration of the liquid crystal display panel would not
be reduced.
[0019] Other features and advantages of the present disclosure will
be further explained in the following description, and partially
become self-evident therefrom, or be understood through the
embodiments of the present disclosure. The objectives and
advantages of the present disclosure will be achieved through the
structure specifically pointed out in the description, claims, and

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0033] The present disclosure will be explained in details with
reference to the embodiments and the accompanying drawings, whereby
it can be fully understood how to solve the technical problem by
the technical means according to the present disclosure and achieve
the technical effects thereof, and thus the technical solution
according to the present disclosure can be implemented. It should
be noted that, as long as there is no structural conflict, all the
technical features mentioned in all the embodiments may be combined
together in any manner, and the technical solutions obtained in
this manner all fall within the scope of the present
disclosure.
[0034] Many specific details are illustrated hereinafter for
providing a thorough understanding of the embodiments of the
present disclosure. However, it is obvious for those skilled in the
art that, the present disclosure can be implemented in other
methods in addition to the details or specifics described
herein.
[0035] FIG. 1 schematically shows a structure of two adjacent sub
pixels of a liquid crystal display panel in the prior art. The
liquid crystal display panel comprises a liquid crystal cell 101, a
flat layer 102, a color resistance layer 103, a glass substrate
104, and a black matrix 105 that is formed on the glass substrate
104. The sub pixel A and the sub pixel B are two adjacent sub
pixels. The color resistance layer 103 which covers the sub pixel A
has a red color, while the color resistance layer 103 which covers
the sub pixel B has a green color. The glass substrate 104, the
color resistance layer 103, the black matrix 105, and the flat
layer 102 jointly constitute a color filter of the liquid crystal
display panel.
[0036] In a Thin Film Transistor (TFT) LCD, an active layer
amorphous silicon (a-Si) in the a-Si TFT is a light sensitive
material. A channel is arranged at a top of TFT in a bottom-gate
element. Therefore, during the using of TFT-LCD, the ambient light
would irradiate the a-Si material of the channel directly, and thus
the performance of TFT would be adversely affected. The channel can
be shaded by the black matrix, so that the ambient light can be
prevented from irradiating the a-Si material of the channel
directly.
[0037] In addition, a gap between two adjacent sub pixels is an
area with no power applied, and the contrast of an image displayed
therein would be reduced seriously if light leakage occurs. The
light leakage phenomenon can be alleviated by the black matrix that
is arranged between the two adjacent sub pixels.
[0038] With respect to a point X of the sub pixel B, a critical
angle .theta..sub.x at which the light
tan .theta. x = p x T PR + T OC + d - T BM ##EQU00001##
that enters from the point X can exactly pass over the black matrix
105 and enter into the sub pixel A can be calculated according to
the following formula (1):
tan .theta. x = p x T PR + T OC + d - T BM ##EQU00002##
wherein p.sub.x represents a distance between the point X and the
boundary of the sub pixel
[0039] A, T.sub.PR represents a thickness of the color resistance
layer, T.sub.OC represents a thickness of the flat layer, d
represents a thickness of the liquid crystal cell, and T.sub.BM
represents a thickness of the black matrix.
[0040] In order to avoid the color mixture phenomenon, the critical
angle .theta..sub.x should be selected as large as possible.
Therefore, it is very important to control the thicknesses of the
layers of the color filter. In general, in order to obtain a
relatively large critical angle .theta..sub.x, the thickness
T.sub.BM of the black matrix should be selected as large as
possible, and at the same time, the thicknesses of the color
resistance layer, the flat layer, and the liquid crystal cell
should be selected as small as possible. However, the optical
properties of the display panel would be changed if the thicknesses
of the layers of the color filter are changed.
[0041] As shown in FIG. 2, with respect to the light that enters
from an intersection point of two adjacent sub pixels, the critical
angle .theta..sub.0 at which the color mixture phenomenon would
occur can be calculated according to the following formula (2):
tan .theta. 0 = L BM 2 ( T PR + T OC + d ) ##EQU00003##
wherein L.sub.BM represents a width of the black matrix.
[0042] In order to reduce the color shift phenomenon of the LCD
under wide viewing angles and keep other optical properties of the
liquid crystal display panel unchanged at the same time, the width
of the black matrix is increased in the prior art. In this case,
however, the aperture ratio and the penetration of the display
panel would be reduced inevitably.
[0043] In order to eliminate the aforesaid defect of the color
filter in the prior art, the present disclosure provides a new
color filter and a liquid crystal display panel comprising the
color filter. According to the present disclosure, the color filter
comprises a color resistance layer, a flat layer, and a first black
matrix, wherein the flat layer is coated on the color resistance
layer, and the first black matrix is not formed on the glass
substrate as the color filter in the prior art, but arranged in the
flat layer instead. In this case, the relative height of the black
matrix can be improved under the condition that the thickness of
the black matrix is not changed, so that the light leakage of the
inclining incident light can be reduced and the color shift
phenomenon of the LCD under wide viewing angles can be
alleviated.
[0044] The principles, structures, and advantages of the color
filter according to the present disclosure will be further
illustrated hereinafter with reference to different
embodiments.
Embodiment 1
[0045] FIG. 3 schematically shows a structure of a liquid crystal
display panel according to the present embodiment.
[0046] As shown in FIG. 3, the liquid crystal display panel
according to the present embodiment comprises a first glass
substrate 301, a first black matrix 302, a color resistance layer
303, a flat layer 304, a liquid crystal cell 305, and a second
glass substrate 306, wherein the first glass substrate 301, the
first black matrix 302, the color resistance layer 303, and the
flat layer 304 jointly constitute a color filter.
[0047] According to the present embodiment, during the
manufacturing of the color filter, the color resistance layer 303
is formed on the first glass substrate 301 first, the first black
matrix 302 is formed on the color resistance layer 303 then, and
the flat layer 304 is formed on the color resistance layer 303 and
the first black matrix 302 at last. According to the present
embodiment, the first black matrix 302 is formed on the color
resistance layer 303 through printing. It should be noted that,
according to other embodiments of the present disclosure, the first
black matrix 302 can be formed on the color resistance layer 303
through other reasonable methods, such as photolithography. The
present disclosure is not limited by this.
[0048] Since the flat layer 304 is coated after the first black
matrix 302 is formed, the first black matrix 302 would not affect
the tape angle between the two adjacent sub pixels, and the gap
between the two adjacent sub pixels would not be increased. It can
be seen that, the fact that the first black matrix 302 is formed on
the color resistance layer 303 would not affect the planar
arrangement of the liquid crystal molecules.
[0049] In the liquid crystal display panel according to the present
embodiment, the thickness of the color resistance layer 303 is 2
.mu.m, the thickness of the first black matrix is 1.2 .mu.m, the
thickness of the flat layer is 2 .mu.m, the thickness of the liquid
crystal cell is 3.2 .mu.m, and the width of the sub pixel is 21
.mu.m. A color mixture diagram and a light leakage diagram of sub
pixels in a dark state under different inclining angles of the
liquid crystal display panel as shown in FIG. 4 can be obtained
through simulation.
[0050] FIG. 5 schematically shows a structure of a liquid crystal
display panel in the prior art. It can be seen through comparing
FIG. 3 with FIG. 5 that, in the display panel in the prior art, the
first black matrix 302 is formed on the first glass substrate 301.
During the manufacturing of the liquid crystal display panel in the
prior art, the first black matrix 302 is formed on the first glass
substrate 301 first, the color resistance layer 303 is formed on
the first glass substrate 301 and the first black matrix 302 then,
and the flat layer 304 is formed on the color resistance layer 303
at last.
[0051] In order to illustrate the advantages of the color filter
and the liquid crystal display panel provided by the present
embodiment more clearly, the thickness of each layer of the liquid
crystal display panel as shown in FIG. 5 is equal to that of a
corresponding layer of the liquid crystal display panel as shown in
FIG. 3. During the analysis, in the two sub pixels as shown in FIG.
3 as well as those as shown in FIG. 5, the left sub pixel is
activated, while the right sub pixel is in the dark state.
[0052] FIG. 6 is a color mixture diagram and a light leakage
diagram of sub pixels in a dark state under different inclining
angles of a liquid crystal display panel in the prior art. It can
be seen from FIG. 4 and FIG. 6 that, according to the present
embodiment, the light leakage of the sub pixels in the dark state
would occur at the horizontal ordinate of [24 .mu.m, 30 .mu.m], and
the light leakage of the sub pixels in the dark state is the most
serious at the inclining angle of 40.degree.. However, compared
with the liquid crystal display panel in the prior art, the light
leakage of the sub pixels in the dark state under different
inclining angles in the liquid crystal display panel according to
the present embodiment is less serious.
[0053] In order to illustrate the advantages of the color filter
and the liquid crystal display panel provided by the present
embodiment more clearly, the present embodiment will be further
explained below taking the light leakage diagrams at each position
of the sub pixels in the dark state of the two kinds of color
filters under the same inclining angle as examples.
[0054] FIG. 7 to FIG. 10 are light leakage diagrams at each
position of the sub pixels in a dark state of a color filter in the
prior art and a color filter according to the present embodiment
under an inclining angle of 20.degree., an inclining angle of
40.degree., an inclining angle of 60.degree., and an inclining
angle of 80.degree. respectively. It can be seen obviously from
[0055] FIG. 7 to FIG. 10 that, under different inclining angles,
the extents of light leakage of the sub pixels in the dark state of
the color filter according to the present embodiment are all lower
than those of the color filter in the prior art.
[0056] FIG. 11 and FIG. 12 are change trend diagrams of
chromaticity coordinates Rx and Ry of a color filter in the prior
art and a color filter according to the present embodiment under
different inclining angles respectively. It can be seen from FIG.
11 and FIG. 12 that, compared with the color filter in the prior
art, the chromaticity coordinates Rx and Ry of the color filter
provided by the present embodiment both change more slowly, which
shows that the color shift generated by the color filter according
to the present embodiment is relatively low.
Embodiment 2
[0057] FIG. 13 schematically shows a structure of a color filter
according to the present embodiment.
[0058] As shown in FIG. 13, the color filter according to the
present embodiment comprises a glass substrate 401, a color
resistance layer 402, a flat layer 403, and a first black matrix
404. During the manufacturing of the color filter, the color
resistance layer 402 is formed on the glass substrate 401 first,
the flat layer 403 is formed on the color resistance layer 402
then, and the first black matrix 404 is formed in the flat layer
403 at last.
[0059] According to the present embodiment, the first black matrix
404 is formed in the flat layer 403 through carbonizing the flat
layer 403 at a position corresponding to a data line. Specifically,
according to the present embodiment, the first black matrix 404 is
formed through irradiating the position corresponding to the data
line of the flat layer 403 by laser. H element and O element of the
flat layer 403 can be removed by the laser irradiation, while C
element is reserved. In this manner, the irradiation position is
changed into black color and thus the first black matrix 404 can be
formed.
[0060] 20
[0061] It should be noted that, according to other embodiments of
the present disclosure, the color filter can be manufactured in a
method similar to the color filter in the prior art. That is, a
second black matrix 405 is formed on the glass substrate 401 first,
the color resistance layer 402 is formed on the glass substrate 401
and the second black matrix 405 then, the flat layer 403 is formed
on the color resistance layer 402 next, and the first black matrix
404 is formed in the flat layer 403 at last. The present disclosure
is not limited by this. In this case, the manufacturing procedures
of the color filter according to the present embodiment are the
same as those of the color filter in the prior art before the first
black matrix 404 is formed, and thus the climbing of the
manufacturing cost resulted from manufacturing procedure changing
can be reduced.
[0062] The present embodiment further provides a new liquid crystal
display panel, as shown in FIG. 14. The liquid crystal display
panel comprises the color filter provided by the present embodiment
and a liquid crystal cell 406. FIG. 15 schematically shows a
structure of a liquid crystal display panel in the prior art.
[0063] It can be seen from FIG. 14 and FIG. 15 that, when the
thickness of each layer of the liquid crystal display panel as
shown in FIG. 14 is equal to that of a corresponding layer of the
liquid crystal display panel as shown in FIG. 15, with respect to a
point Y of the left sub pixel, the critical angle at which the
light that enters from the point Y can exactly pass over the black
matrix and enter into the right sub pixel of the liquid crystal
display panel according to the present disclosure is larger than
the critical angle of the liquid crystal display panel in the prior
art. Similarly, with respect to the light that enters from an
intersection point of two adjacent sub pixels, the critical angle
at which the color mixture phenomenon would occur in the liquid
crystal display panel according to the present disclosure is also
larger than the critical angle of the liquid crystal display panel
in the prior art. Therefore, the color shift phenomenon under wide
viewing angles can be alleviated by the color filter and the liquid
crystal display panel provided by the present embodiment.
[0064] FIG. 16 and FIG. 17 are change trend diagrams of
chromaticity coordinates Rx and Ry of the color filter in the prior
art, the color filter provided by embodiment 1, and the color
filter provided by the present embodiment under different inclining
angles respectively. It can be seen from FIG. 16 and FIG. 17 that,
compared with the color filter in the prior art and the color
filter provided by embodiment 1, the chromaticity coordinates Rx
and Ry of the color filter provided by the present embodiment both
change more slowly, which shows that the color shift generated by
the color filter according to the present embodiment is relatively
low. Therefore, the color shift phenomenon under wide viewing
angles of the liquid crystal display panel can be alleviated.
[0065] It should be noted that, the color filter and the liquid
crystal display panel as mentioned above are mainly used in
In-Plane Switching (IPS) panel, which does not comprise a
corresponding Indium Tin Oxide (ITO) layer (such as a common
electrode layer) on the above side of the liquid crystal layer
(i.e., in the color filter). However, it does not mean that the
technical solution provided by the present disclosure is only
applicable for the IPS liquid crystal display panel. The technical
solution provided by the present disclosure can also be used in
other types of display panels according to actual needs, and the
present disclosure is not limited by this. For example, according
to one embodiment of the present disclosure, the liquid crystal
display panel can also be a Twisted Nematic (TN) panel. In the TN
panel, the color filter further comprises a common electrode layer,
which is formed on the flat layer.
[0066] It can be seen from the above description that, in the color
filter according to the present disclosure, the critical angle of
the color shift phenomenon can be improved effectively, and at the
same time, the thickness of each layer of the color filter and the
width of the black matrix do not need to be changed. Therefore,
other optical properties of the liquid crystal display panel would
not be changed. Since the width of the black matrix is not
increased, the aperture ratio and the penetration of the liquid
crystal display panel would not be reduced.
[0067] It could be understood that, the embodiments disclosed
herein are not limited by the specific structures, treatment steps
or materials disclosed herein, but incorporate the equivalent
substitutes of these features which are comprehensible to those
skilled in the art. It could be also understood that, the terms
used herein are used for describing the specific embodiments, not
for limiting them.
[0068] The phrases "one embodiment" or "embodiments" referred to
herein mean that the descriptions of specific features, structures
and characteristics in combination with the embodiments are
included in at least one embodiment of the present disclosure.
Therefore, the phrases "one embodiment" or "embodiments" appeared
in different parts of the whole description do not necessarily
refer to the same embodiment.
[0069] For the purpose of convenience, a plurality of items,
